29 * Change Activity-
30 *
31 * Date Description of Change BY
32 * --------- --------------------- ---
33 * 09-Sep-98 Created MCG
34 * 02-Nov-98 Removed External arbiter selected message JWB
35 * 27-Nov-98 Zero out PTMBAR2 and disable in PTM2MS JWB
36 * 04-Jan-99 Zero out other unused PMM and PTM regs. Change bus scan MCG
37 * from (0 to n) to (1 to n).
38 * 17-May-99 Port to Walnut JWB
39 * 17-Jun-99 Updated for VGA support JWB
40 * 21-Jun-99 Updated to allow SRAM region to be a target from PCI bus JWB
41 * 19-Jul-99 Updated for 405GP pass 1 errata #26 (Low PCI subsequent MCG
42 * target latency timer values are not supported).
43 * Should be fixed in pass 2.
44 * 09-Sep-99 Removed use of PTM2 since the SRAM region no longer needs JWB
45 * to be a PCI target. Zero out PTMBAR2 and disable in PTM2MS.
46 * 10-Dec-99 Updated PCI_Write_CFG_Reg for pass2 errata #6 JWB
47 * 11-Jan-00 Ensure PMMxMAs disabled before setting PMMxLAs. This is not
48 * really required after a reset since PMMxMAs are already
49 * disabled but is a good practice nonetheless. JWB
50 * 12-Jun-01 stefan.roese@esd-electronics.com
51 * - PCI host/adapter handling reworked
52 * 09-Jul-01 stefan.roese@esd-electronics.com
53 * - PCI host now configures from device 0 (not 1) to max_dev,
54 * (host configures itself)
55 * - On CPCI-405 pci base address and size is generated from
56 * SDRAM and FLASH size (CFG regs not used anymore)
57 * - Some minor changes for CPCI-405-A (adapter version)
58 * 14-Sep-01 stefan.roese@esd-electronics.com
59 * - CONFIG_PCI_SCAN_SHOW added to print pci devices upon startup
60 * 28-Sep-01 stefan.roese@esd-electronics.com
61 * - Changed pci master configuration for linux compatibility
62 * (no need for bios_fixup() anymore)
63 * 26-Feb-02 stefan.roese@esd-electronics.com
64 * - Bug fixed in pci configuration (Andrew May)
65 * - Removed pci class code init for CPCI405 board
66 * 15-May-02 stefan.roese@esd-electronics.com
67 * - New vga device handling
68 * 29-May-02 stefan.roese@esd-electronics.com
69 * - PCI class code init added (if defined)
